Simulate a sticky fluid in Blender
As far as I know this is not possible with fluid simulation itself. The fluid sim does not do sticking itself to a surface as a feature (sometimes you get it as a bug).

Workarounds i can think of:


Stop the fluid sim at the point where it should stick and apply the modifier making the mesh solid.
Use dynamic paint modifier with the fluid sim mesh as a brush. Use the resulting paint output with a bump map to give it some texture.
